Tried with :
kern.version=OpenBSD 6.1-current (GENERIC) #84: Tue May 30 21:02:10 MDT 2017
    [email protected]:/usr/src/sys/arch/amd64/compile/GENERIC

Same problÃem.
Seems to be more obvious on port 22 with infinit loop (ie. for(;;))

Only tested on a VM this time. Will try on real hardware as soon as possible.
